Condition

Risky alcohol use, alcohol abuse or addiction

Intervention

1. Two versions of a fully automated self-help intervention for adolescents and young adults with risky alcohol use are compared2. Both versions of change your drinking begin with a self-test (check your drinking), which gives a personalised feedback3. The aim of change your drinking is to reduce or to drinking4. In detail, participants should not drink more than 24g/12g (m/f) pure alcohol per day5. They can even choose to drink less or abstain from drinking6. After registration participants get access to a drinking diary7. In the original program the drinking dairy can be filled out for 10 days and participants receive a short personalised feedback at the end8. The modified version lasts 14 days and consists of additional interactive elements:8.1. Participants receive short personalised feedbacks every day and longer feedbacks 7 and 14 days after registration8.2. Every day participants are advised to reflect their personal risk situations and to develop strategies in order to cope with those situations (relapse prevention)8.3. Participants are encouraged to reward themselves for achieving their personal goal8.4. The drinking diary can be extended for additional 14 days, but without personalised feedback9. The program is open to the general public10. Eligibility criteria will be checked after completion of the self-test check your drinking 11. Users who do not meet criteria or do not want to participate on the study receive the original version of change your drinking
